| FROM E.{Mr Elliott - Chief Engineer} Copy to HS.{Lord Ernest Hives - Chair} re. SYLPHON TUBING FOR PETROL PUMP. x2677. ORIGINAL We believe you went into the question of what was the smallest size of sylphon tube which could be obtained, and we should be glad if you could kindly send us particulars of what you found was available. We have in hand a design for a mechanically operated petrol pump for the chassis, and we propose to use a sylphon bellows with about a .050 stroke and lightly loaded poppet valves.
